Ryan Giggs has denied a rift with David Moyes as the midfielder insisted Manchester United were not underdogs against Bayern Munich in the Champions League quarter-final.

Pep Guardiola's team are the holders and firm favourites going into Tuesday evening's first leg at Old Trafford against a United side seventh in the Premier League, 17 points behind the leaders, Liverpool.

Moyes' disappointing first season in charge had led to rumours that Giggs, who is player-coach, has failed to see eye-eye with the Scot on football issues. Although it is understood that the Welshman has taken a lesser role during training, he was seen in discussion with Moyes during Monday morning's session.

Giggs, seated next to the 50-year-old for the press conference before Bayern's visit, was asked how he got on with Moyes and being underused as player this campaign.

He said: "There is no problem with the manager; I don't know where that came from. The relationship is good. Of course as a player you want to play all the time. I know over the last five or six years you are not going to play every game. I normally play every two or three weeks to get the best out of me. The last game was probably my first for seven weeks but you are not sulking, you just have to be ready to play your best for the team."

Giggs' 12-month deal ends this summer, yet he would not be drawn on whether this could be his last European campaign, stating that playing on will be considered. "I don't know. I'll tell you after tomorrow [Tuesday]," he said. "I am just trying to enjoy this season and then at the end I will take stock and see what I want to do. I am enjoying my football as much as ever, I feel fit and then at the end of the season, I will see what I want to do."

Giggs, a member of the United team that triumphed over Bayern in the 1999 final, admitted the German club's current side are a formidable foe but refused to bill them as favourites.

"Bayern are a fantastic team, they are the holders and Pep Guardiola has taken over and added a few new players and they are a very strong team, favourites in most people's eyes. But we are Manchester United, and at Old Trafford we have had so many great nights. We don't see ourselves as underdogs, we see ourselves as Manchester United playing at home."

Sir Alex Ferguson, Moyes' predecessor, has been blamed in some quarters for United's disappointing campaign, with questions raised about the strength of the squad he left. Moyes himself claimed Ferguson might have struggled this term because of the "ageing" nature of some players but Guardiola denied the 71-year-old could be viewed as at all culpable.

The Spaniard, who in his first season at Bayern won the Bundesliga with seven games to spare, did not speak directly of Moyes' comments. But he did say: "I don't know how Sir Alex Ferguson can have a bad influence on this club. It's completely opposite. This club was the best club in England thanks to him. He reorganised the club and put the club on another level in this country."

Moyes wants to sign Toni Kroos, the Bayern midfielder. But Guardiola said: "Toni has one year more of a contract and Toni will remain. I hope he can extend his contract and stay with us because he is a very good guy, he loves his game. It is not just a job for him and I would like him to stay but I spoke with the player, with the club, I gave my opinion. After that I am not manager, I am just the trainer."
